Deleage was a French citizen who joined Sofinnova Partners in the early 1970s, and several years later opened up the firm’s San Francisco office. He founded Burr Egan Deleage & Co. in 1970, which for more than 20 years was one of the nation’s leading, and largest, venture capital groups. The firm ultimately split into four successor groups: Alta Partners, Alta Communications, Alta Berkley and Polaris Venture Partners – with Deleage sticking with healthcare-focused Alta Partners.
In an emailed statement, Alta Partners said:
Former partner Bill Egan added: “Jean was ‘one of a kind’ that we will miss greatly. He was not only a great investor and partner but an even better friend.”
Our deepest condolences to Jean’s friends and family. When memorial information is available, we’ll be sure to pass it on.
